See your KLM dealer or write for a catalog. After a few years of exper- imentation and further de- velopments, I succeeded in writing a total of six RTTY programs for the In order for a number of stations to be on one fre- quency at one time with a variety of transmissions, ACKs, and so forth all going on, a computer network, not unlike a typical amateur net, must be established. A license renewed during Ihe grace period will be dated currently and will not be backdated to the date of its expiration.

Jusi fill out the coupon and reium ii to: Indeed, there are some stations using packets that have modified their per- sonal computers to act as TNCs, with varying degrees of success The problems arise from two primary sources: The con- nector is available from Electrovalue or can be ordered specially by your local Apple dealer.

The Apple II 2n33924 Guide” is an excellent refer ence which also covers oth- er topics of interest such as differences between the two Apple Basics, hardware in- terface, etc. Photos by Steven Ybarrola tacts which don’t sound right is the ham who fum- dtaasheet his own call more than once or twice in a CQ.

There are mother- boards available for the Ap- ple II computer from legiti- mate sources. Among those deletions was the requirement of a CW ID for amateurs using video and some common digital codes. One of the most important fea- tures of the RTTY program is that it can be saved any- where in the CoCo’s memo- ry without changes. And not one, but two layers of low dielectric loss, heat-shrinkable tubing protect the element, while a top coat of PVC provides a sleek finish. Call today for information on our terminal units!


Again, I have to stress that much of 2n924 is subject to change with little notice. Stations must be able to check in and out of the net at will. Once the TNC has been told where to send the message, it starts breaking the text into pack- ets which are then sent datashedt on the network. CW-2fl r ; As the plans for Dr Gar- riott’s historic mission move forward, there will doubt- less be many changes taking place For example, the ex- act list of frequencies for you to use may not be known until just prior to lift- off.

Heralding in the spring was the Mount Giiboa March. I’m sure that next year’s contest committee will rectify the matter. For example, the RTTY program’s first instruction is 1 F and is loaded into memo- ry at address The famous Microlog CW decoding algorithms, superior computer enhanced RTTY detection, all the features that have made Microlog terminals the standard by which others are com- pared.

It is up to the user to work up the actual radio inter- face A group of amateurs met in Tucson in November,and decided to get in- volved in packet radio. Amateurs, pilots, and educators can now receive the same graphic printouts of high-quality, detailed weather charts and oceanographic data used by commercial and government personnel. It took me just 53 days on the air to contact all states.

FCS — 2 bytes. The word that I was thinking of selling began to spread, and new suitors started calling every few days, The more I talked with these firms, the more I realized that this probably was a good time to merge with a larger firm so that I would have datashret money to invest in some new projects.

There are many articles about how to make a small computer using various microproces- sors, but after all the effort of gathering parts, wiring, assembly, and testing, you may be left with a system that has no readily-available software and is without a lot of flexibility. It’s a good feeling.

As I talked with people, I datasheeet that I have a pretty good track record.

An astro- ham in space on 2 meters,” Alan, who produces NBC Nightly News for the west coast did not pen those words for that vehicle, Rather, they were darasheet lead-in to a 2-minute special report by Roy Neal K6DUE which aired on my West link Radio News Service, It was a story that took the world of amateur radio by storm, and one which will hopefully unfold on Sep- tember 30, We adopted the mum-num- ber system common to most countries around the world.


This haphazard procedure is not to be recommended if you value your equipment. And if s dataasheet through software so it ‘li never become obsolete.

2N – UHF/VHF Power Transistors

To key in a pro- gram, the left-hand column is the address in memory where the instruction is stored The following bytes are the actual bytes in mem- ory. This mode is called packet radio, and it opens the door to a new world of computer- based communications for the amateur community Imagine having a QSO with an amateur a continent away via a low-power 2- meter FM rig, or handling emergency traffic without worrying if you correctly copied the spelling of Solz- henitsyn, or leaving a mes- sage at a friend’s shack if he is out Then there are possi- bilities for bulletin-board systems, remote program- ming of computers, file trans- fers, and even multi-player computer games!

This instruction allows for an index register to be loaded with the address of a program variable relative to the program counter PCR wherever it may be in mem- ory.

By switching between these tones, the data is passed to the radio, which handles it like any other audio signal. Passion the test at wpm dztasheet and receive Is a prerequisite of datqsheet full HF-class A license.

If you have or can obtain an old vintage typewriter, you will discover that most of them have the same spacing as the RTTY machine Many old typewriters can be picked up at attractive prices.

Why Use a Terminal Node Controller? The best known incoming bureau is m Halifax.

The Society of Wireless Pioneers is datasjeet to reprint ihe sencs soon, and I hope more of you will get the chance to read these memoirs of a radio operator In the pre- WWII era of radio. If you are not blessed with such an art- ist, fear not You need not be a great artist to accomplish this task. Operator — The amateur operator is you!
